The permissible operating temperature for tapered roller bearings can be limited by:
- the dimensional stability of the bearing rings and rollers
- the cage
- the lubricant
When temperatures outside the permissible range are expected, contact the SKF application engineering service.
Bearing rings and rollers
SKF tapered roller bearings undergo a special heat treatment. The bearings are heat stabilized up to:
- D ≤ 160 mm → 120 °C (250 °F)
- D > 160 mm → 150 °C (300 °F)
Steel or PEEK cages can be used at the same operating temperatures as the bearing rings and rollers. For temperature limits of cages made of other polymer materials, refer to Cage materials.
Temperature limits for SKF greases are provided under Lubrication.
When using lubricants not supplied by SKF, the temperature limits should be evaluated according to the SKF traffic light concept.
